That would be a no. This is JavaScriptCore, even when Chrome was using WebKit they were not using JavaScriptCore but V8. Also considering it only gives a speed-up of 20% in exchange for massive memory usage increase, bundling a full compiler, big increase in complexity and several manyears of work; FTL doesn't even look that great.

Did someone pee in your cereal this morning or are you an Internet Explorer developer?

I am a WebKit developer. Though my perception of FTL might be tainted by the fact that when it was merged in July 2013, it managed to break everything. JavaScriptCore was unusable for more than a month after the FTL merge even though FTL was not even enabled. Not really the best of starts and it lowered my expectations of FTL dramatically (plus demonstrated the cost of added complexity even when disabled).

The webkit developers behind it are saying it will be a 33% increase. (Over the existing 3rd tier compiler). 40 times faster than interpreted vs. the 30 times faster they can already go.

That really just brings them back on par with their competition, it's not like this is a huge breakthrough, at least in performance. Maybe now that they've got the framework done they'll be able to get some more benefits from it soon, though.
